hyperlight-wasm calculator example

THis is an example of a hyperlight-wasm application that runs a wasm component inside a hyperlight-sandbox that implements a calculator (similar to the component model example here).

The calculator itself is comprised of three wasm components:

• calculator - the main component that implements the calculator interface (written in Rust)
• adder - a component that implements the addition operation (written in Rust)
• subtractor - a component that implements the subtraction operation (written in Javascript)
• Additionally there is a multiply operator that is implemented as a hyperlight host function.

The example program loads the composed calculator/wasm component into a hyperlight-sandbox along with a wasm runtime and invokes functions as hyperlight-guest calls.

Requirements

To build and run this example, you need the following tools installed on your system:

• Rust toolchain including x86_unknown-none target
  • https://www.rust-lang.org/tools/install
• Node.js (to build the subtractor wasm component)
• wasm-tools
• wac
• cargo component
• hyperlight-wasm-aot
  • cargo install --git https://github.com/hyperlight-dev/hyperlight-wasm hyperlight-wasm-aot
• Just
